ID this poem?

I read a poem in a college lit class and have searched for it unsuccessfully in the intervening years. It was a poem about a funeral–more precisely, about the carrying of the deceased to the burial–in which the corpse is accidentally allowed to fall from the coffin and…well…roll downhill. It was darkly funny.

I remember the author as Gwendolyn Brooks, but time clouds memory and I may be way off the mark. In any case, help is most appreciated.

Seems a little like As I Lay Dying mixed with Brooks’s “the rites for Cousin Vit”. But neither of those are particularly close matches.
